Abrasion-resistant efficient noise-damping circular saw blade

Abstract

An abrasion-resistant efficient noise-damping circular saw blade comprises a saw blade substrate, wherein the saw blade substrate comprises a saw body substrate and saw teeth; and a central hole is formed in the saw body substrate. The circular saw blade is characterized in that a plurality of noise-damping slots are formed in the saw body substrate; a plurality of noise-damping slits are also formed in the saw body substrate; tooth slots are formed among the adjacent saw teeth, and comprise shallow tooth slots and deep tooth slots; grooves are formed in the saw teeth; the noise-damping slotsare circular and connected through the noise-damping slits; the noise-damping slits are arc-shaped; and the deep tooth slots are formed at intervals of 2 to 3 hollow tooth slots. The circular saw blade has an obvious weakening effect on vibration noise; through the combined connection between the noise-damping slots and the noise-damping slits, the slotting and slitting space of the circular saw blade can be effectively reduced and the rigidity of the circular saw blade can be improved; the saw teeth adopt a structure of different toot slot depths, so that aerodynamic noise can be effectivelyreduced; and meanwhile, cuttings can be effectively discharged from the deep tooth slots in the cutting process, the saw body substrate can be prevented from being abraded by the cuttings, and the service life of the circular saw blade can be prolonged.

Description

technical field [0001] The invention relates to a wear-resistant and high-efficiency sound-absorbing circular saw blade, which belongs to the field of cutting processing. Background technique [0002] The saw blade rotates at high speed during idling and cutting, which generates noise enough to endanger human health. In order to reduce the noise, in the past, the base of the saw blade was usually provided with sound-absorbing grooves or slits. The sound-absorbing effect of opening the silencing grooves and slits alone is average, but with the sound-absorbing grooves and slits at the same time, it needs to occupy the area of ​​the saw body. Larger, resulting in insufficient rigidity of the saw body, easy to crack, reducing the reliability and life of the saw blade. Slots on the saw body are mostly used to reduce vibration noise, and the control of aerodynamic noise when the saw blade is idling is insufficient.
